3.1 Processor
The MI5VP4 motherboard is designed to take Socket 7 processors with
system speed of 120MHz to 500MHz at a bus speed of 60MHz to
124MHz. To be able to use the your processor with the motherboard
properly, DIP switches on the motherboard should be configured
correctly. Two DIP switches are available to configure the CPU voltage,
bus speed (front side bus), and bus speed multiplier. Please refer to the
following chapter on how to configure the CPU frequency.
3.2 L2 Cache
The L2 cache is integrated in the processor.
3.3 Main Memory
The MI5VP4 motherboard supports three 168-pin DIMM (Dual In-line
MemoryModule) sockets to forma memory configuration from 32MB to
384MB. DIMM modules can be 32MB, 64M and128MB in SDRAM. In
populating the DIMM sockets, any socket can be populated first. Refer to
the following table on how to do the memory configuration.
NOTE: Use SDRAM modules with PC100 specification when running
100MHz CPU bus speed. With 66MHz CPU bus speed, SDRAM
modules with PC66 or PC100 specification can be used.

3.4 BIOS
The BIOS on the MI5VP4 motherboard provides the standard BIOS
functions plus the following additional features:
1. ISA Plug and Play (PnP) Extension
Unlike PCI cards that are Plug and Play, ISA cards require setting
jumpers to resolve hardware conflicts. To make a computer system
PnP, an ISA PnP standard is established and supported by new
operating systems, such as Windows 95. Under Windows 95, the
motherboard BIOS must have an ISA PnP extension to support new
ISA PnP cards.
2. Power Management
The power management feature provides power savings by slowing
down the CPU clock, turning off the monitor screen and stopping the
HDD spindle motor. The BIOS fully conforms to ACPI (Advanced
Configuration and Power Interface) specification.
3.5 Onboard VGA
The Apollo MVP4 Graphics Controller is a highly integrated display
control device that incorporates a 64-bit 3D/2D graphic engine and video
accelerator with advanced DVD video capability. It provides a flexible
and high performance solution for graphics and video playback
acceleration for various color depth and resolution modes. It supports a
full AGP implementation that include direct access of the system memory
by the 3D engine to provide increased texture memory.
3.6 Hardware Monitoring
The VIA VT82C686A chip has a built-in hardware status monitoring
function that monitor several hardware parameters including power
supply voltages, fan speeds, and temperatures, which are very important
for a high-end computer system to work stable and properly. This
function is used together with System Monitor utilityor the optional Intel
LANDesk Client Manager utility.
3.7 Onboard Multi-I/O
The multi-I/O function is built in the VIA VT82C686A chip supports a
keyboard controller, two serial ports, one parallel port, one floppy
controller and one IrDA port. The serial ports are 16550 UART
compatible. The parallel port features high-speed EPP/ECP mode. The
floppy controller supports up to 2.88MB format.

Chapter 3 Hardware Description
10 MI5VP4 User’s Manual
3.8 Interrupt Request (IRQ) Lines
There is a total of 15 IRQ lines available on the motherboard. Peripheral
devices use an interrupt request to notify the CPU for the service
required. The following table shows the IRQ lines used bythe devices on
the motherboard:
Level Function
IRQ0 System Timer Output
IRQ1 Keyboard
IRQ2 Interrupt Cascade
IRQ8 Real Time Clock
IRQ9 Software Redirected to Int 0Ah
IRQ10 Reserved
IRQ11 Reserved
IRQ12 Reserved
IRQ13 Co-Processor
IRQ14 Primary IDE
IRQ15 Secondary IDE
IRQ3 Interrupt
IRQ4 Serial Port #1
IRQ5 Interrupt
IRQ6 Floppy Disk Controller
IRQ7 Parallel Port #1
3.9 Onboard PCI-IDE
The VIA VT82C686A chip built-in’s PCI-IDE controller supports PIO
mode 3/4 and bus mastering Ultra DMA 33/66. The peak transfer rate of
PIO mode 3/4 can be as high as 17MB/sec. Using HDDs that support
Ultra DMA66, the peak transfer rate can reach 66MB/sec. There are two
IDE connectors - primary IDE and secondary IDE. With two devices per
connector, up to four IDE devices can be supported.
3.10 DMA Channels
There are seven DMA channels available on the motherboard; only
DMA2 is used by the floppycontroller. In the case that ECP mode on the
parallel port is utilized, DMA1 or DMA3 will be used.

3.11 I/O Port Address Map
Each peripheral device in the system is assigned a set of I/O port
addresses which also becomes the identity of the device. There is a total
of 1K port address space available. The following table lists the I/O port
addresses used on the motherboard.
